We found this odd-looking plant growing on a moss-covered boulder in a Vermont sugarbush. What is it?
Answer
Walking Fern.
The walking fern (Asplenium rhizophyllum) – known in some areas as walking spleenwort – got its name from its ability to “walk” across the ground: when the frond tips touch moist ground, a new fern can grow, so the plant seems to be moving. Look for these special ferns on moss-covered limestone boulders. Walking fern is identified as endangered or threatened in many states; it’s extirpated in Maine.
